Hi Guys, need some help here, I’m a complet noob to linux so please be gentle . step by step would help I’ve tried to get some scripts working but after 3 days yes three days of going around in circles , I,m here.
[ “$1” = “on” ]; then
gpioset --mode=exit gpiochip0 17=1
else
gpioset --mode=exit gpiochip0 17=0
fi
No mater what I do I get 2025-02-25 13:53:00.557] ERROR[17397]: app_rpt.c:748 rpt_event_process: event exec item malformed: /bin/sh /usr/local/bin/rx_led.sh 1
[2025-02-25 13:53:00.557] ERROR[17397]: app_rpt.c:748 rpt_event_process: event exec item malformed: /bin/sh /usr/local/bin/rx_led.sh 0

I give up, any one got a step by step idiots guide .
Thanks in advance

Can you paste in the configuration snippet from rpt.conf you’re using?

Also, enclosing your posted code and configuration in three backticks → ``` before and after helps with readability.

You’re mixing direct GPIO control wth scripts. You can do cop to call an internal command or cmd to call an external command. But you can’t mix-and-match. Try this:

91 = cop,61,GPIO17=1
92 = cop,62,GPIO17=1
93 = cop,61,GPIO17=0

alternatively:

91 = cmd,/usr/local/bin/tx_led.sh 1
92 = cmd,/usr/local/bin/rx_led.sh 1
93 = cmd,/usr/local/bin/tx_led.sh 0

I’ll have to put the LEDS on hold for a while, either rx is smoked or the cm108 chip. I chase you up when its back up and running.
